Are you doing mostly gi or no-gi BJJ? I would suggest that you also include grip strength training. Then again, if I were you, I'd just throw all that **** out the window, do bodyweight exercises and lots of stretching, and go to BJJ more often. Unless you have a specific weight class you want to be in, or a specific weight gain, what's the point of training for grappling when you could just be grappling a lot?

It depends on yur goals I guess wether you can pull/push horizontaly and vertically (like pullup + row) on the same day. If you want to get as strong as you can, or get to a certain strength level quickly, I would say split them up. My goal personally for now is to get allmy lifts up to a certain number. Therefore I split them up but still do full body.

Example is I row one day and pullup the next so that I can focus exclusively on each workout on one pull. If you bench, row, squat one day and overhead, pullup, dead the other day you are still doing full body workouts each time, and can focus more on going heavy for each one.

However my goals and yours are different. I found bodyweight exercises are really improving my cardio a lot on the mat. If your main goal is to get stronger lift heavy full body. If it cardio then do BW or HIIT (I only do BW at the moment). If it is more skill go to BJJ more.

Analize your game, its weaknesses and then decide what to focus on in your free time (flexibility, skill, power, explosiveness, cardio etc.)

so far I've been experimenting with different ways to work the grip and tendon strength and here's a quick breakdown of it

5 exercises x 5 rotations
20 secs per exercise 10 sec rest 4xweek
1. hanging clean and jerk
(but instead or using just the bar use 2 squat pads for the grips to closely simulate someone's wrists)
2. power band pulls
(again use the squat pads or towels as grips exposivly pulling to the sides and straight between the legs)
3. explosive jump and pulls
(use 2 towels for grips on a chin-up bar and explosively jump up using just your calves and pull up)
4. kettle ball swings
(both sides)
5. medicine ball burpees.

afterward I do 4 sets of 10 reps of 3 different various powerband pulls using the squat pad as grips pulling straight back and to the sides with different arm positions using the core to turn the body. at first when I started this I could only do 3 rotations before being completely smoked, my cardio has gotten better but the gripping of the squat pad is still tough as **** and your forearms will be on fire after the 2nd rotation. Overhead tire throws in an open field is also a great exercise to not only strengthen the foreams and grip but your core muscles and cardio also.
